Project description:In the current study, we reported our initial experience of gasless transoral endoscopic thyroidectomy vestibular approach (TOETVA) by novel trocars and a suspension system. Between February 2019 to September 2020, thyroid cancer patients with indicated central lymph node metastasis by imaging examination who had received gasless TOETVA by our designed trocars and suspension system in The First Affiliated Hospital of University of Science and Technology of China were reviewed. A total of 95 thyroid cancer patients that received gasless TOETVA were included in this analysis. Of note, 73 cases underwent one-sided lobectomy and the remaining 22 cases underwent total thyroidectomy. All thyroid cancer patients underwent central lymph node dissection (CND). The average total examined lymph nodes number was 8.55 ± 5.67 per individual. No serious complications occurred during or after the operation besides one patient who had a short-term recurrent laryngeal nerve (RLN) deficit and one patient who had delayed postoperative bleeding. In conclusion, the use of novel trocars and a suspension system can effectively improve the safety and efficacy of TOETVA.

Project description:The safety and efficacy of the transoral endoscopic thyroidectomy vestibular approach (TOETVA) continues to be verified with the growing literature in regards to the procedure. While early cases were thyroid lobectomies performed for benign disease, the indications for TOETVA have now expanded to include total thyroidectomy for select small well-differentiated thyroid cancers (DTCs). Oncologic efficacy of this procedure remains unproven at this time, as the procedure was described only recently. Furthermore, as many of the cases completed via TOETVA are often diagnostic lobectomies, the appropriate management for patients requiring or opting for further surgical intervention per American Thyroid Association (ATA) guidelines has not been established. Here we present a case of a diagnostic lobectomy via TOETVA followed by interval completion thyroidectomy via the same approach for minimally invasive Hurthle cell carcinoma. Postoperative ultrasound demonstrated no evidence of thyroid remnant and serum thyroglobulin without circulating anti-thyroid antibodies was 0.3 ng/mL (reference range, 1.5-38.5 ng/mL) following the patient's completion thyroidectomy.

Project description:BackgroundIn search of an ideal cosmesis, transoral endoscopic thyroidectomy via vestibular approach (TOETVA) has recently been introduced to avoid a visible scar. Although ambulatory thyroid surgery is considered safe in carefully selected patients, this remains unclear for TOETVA.MethodsAll consecutive adult patients who underwent ambulatory TOETVA or open thyroid surgery at a French university hospital were prospectively enrolled from 12/2020 until 11/2021. The primary outcome was postoperative morbidity (recurrent laryngeal nerve (RLN) palsy, re-intervention for bleeding, wound morbidity, or hospital readmission). The secondary outcome was quality of life (QoL), measured by a survey including a validated questionnaire (SF-12) and a modified thyroid surgery questionnaire six weeks after surgery.ResultsThroughout the study period, 374 patients underwent a unilateral lobectomy or isthmectomy in ambulatory setting, of which 34 (9%) as TOETVA (including 21 (62%) for a possible malignancy). In the TOETVA group, younger age (median 40 (IQR 35-50) vs. 51 (40-60) years, P < 0.001) and lower BMI (median 23.1 (20.9-25.4) vs. 24.9 (22.1-28.9) kg/m2, P = 0.001) were noted. No cases were converted to open cervicotomy. TOETVA was at least as good as open cervicotomy with nil versus four (1%) re-interventions for bleeding, one temporary (5%) versus 13 (4%) (temporary) RLN palsies, and one (<1%) wound infection (open cervicotomy group). No hospital readmissions occurred in all ambulatory surgery patients. No differences were found in physical (P = 0.280) and mental (P = 0.569) QoL between TOETVA and open surgery.ConclusionsIn carefully selected patients, the feasibility and safety of ambulatory TOETVA are comparable to open surgery.

Project description:AbstractFor most primary substernal goitre (SG) surgeries, sternotomy is required because the blood supply vessels of tumours come from the mediastinum. However, sternal dehiscence may lead to several surgical complications. We reported an older patient who underwent simultaneous removal of a primary SG and parathyroid adenoma through a gasless transoral endoscopic approach. The patient recovered well with no hoarseness, post-operative bleeding or other complications after the operation. To the best of our knowledge, this is the first reported case of gasless transoral endoscopic parathyroid adenoma and primary SG resection in the real world. We found that gasless transoral endoscopic surgery is feasible in patients with small primary SG and parathyroid adenoma.

Project description:ObjectivesIntraoperative neuromonitoring has not been routinely applied in early experience with the transoral endoscopic thyroidectomy vestibular approach (TOETVA). Because the preparation and surgical interventions are much different from conventional thyroidectomies, most endocrine surgeons willing to adapt to TOETVA lack access to information regarding the practice pattern and proficiency in the learning curve. We aimed to investigate the outcomes and to define the learning curve for TOETVA in this study.MethodsA retrospective analysis was used on patients who underwent TOETVA at our hospital between December 2016 and July 2019. The cumulative sum graphic model was used to implement the learning curve as a surrogate for procedural proficiency.ResultsThe 119 patients had a mean age of 44.65 years and a mean body mass index of 22.49 k/m2, including 107 women, 20 thyroiditis, and 106 hemithyroidectomy. The learning curve revealed two phases, an initial (35 cases) and a mature (84 cases) phase, for surgeons based on operation time (144.2 vs. 114.2 min, p = 0.0001). There were more bilateral thyroidectomies (15.5% vs. 0, p = 0.0100), larger indicated nodules (6.06 cm3 vs. 3.32 cm3, p = 0.0468), or larger thyroids to resect (16.38 cm3 vs. 8.75 cm3, p = 0.0001) in the mature phase. Procedure-related complications decreased significantly in the mature phase in comparison to the initial phase (3.57% vs. 31.43%, p = 0.0001).ConclusionsThe learning curve of TOETVA with neuromonitoring is 35 cases. With the accumulation of proficiency, the indications will expand. Step-by-step improvements from the experience of each case can reduce procedure-related complications.

Project description:Background:The transoral endoscopic thyroidectomy vestibular approach (TOETVA) is the most recently introduced method of minimally invasive thyroid surgery. To our knowledge, no studies have compared TOETVA outcomes using different laparoscopic systems. This study compared outcomes of TOETVA using conventional high definition (HD) and ultra-high definition (UHD) equipment. Methods:Medical data and surgery videos of 62 patients who randomized to undergo thyroid lobectomy by TOETVA using an HD or UHD system from August 2018 to April 2019 were retrospectively reviewed. Endoscopic procedures were divided into four phases: flap creation to isthmectomy (phase I); strap muscle division to upper pole ligation (phase II); trimming recurrent laryngeal nerve (phase III); and ligation of Berry's ligament to complete resection (phase IV). Results:Of the 62 patients, 28 underwent TOETVA using an HD device and 34 using a UHD device. The clinical characteristics of the two groups were not different. Mean operating time for lobectomy was similar in the HD and UHD groups (44.19±9.94 versus 43.47±12.19 min, P=0.825). The times required for phases I (15.02±5.33 versus 13.67±5.44 min, P=0.397); II (12.89±2.84 versus 13.17±5.22 min, P=0.816); III (9.85±4.36 versus 9.98±4.55 min, P=0.918); and IV (6.43±3.69 versus 6.65±3.45 min, P=0.840) were also similar in the HD and UHD groups. The numbers of retrieved lymph nodes did not differ significantly in the HD and UHD groups (3.26±2.62 versus 3.45±2.81, P=0.807). Conclusions:Applying a UHD system in TOETVA resulted in outcomes similar to those observed with a conventional HD system. Operation time tended to be lower, especially for flap dissection, and numbers of harvest lymph nodes tended to be higher in the UHD group. Large-scale studies are needed to assess the advantages of the UHD system.

Project description:Recently, transoral endoscopic thyroidectomy (TOET) is receiving attention because it is regarded as a true minimally invasive surgery in that it does not leave scars on any part of the body and the area of flap dissection is similar to that of open surgery. In this study, we present the surgical procedures and initial outcomes of TOET in the treatment of papillary thyroid microcarcinoma (PTMC) patients.The medical records of patients who underwent TOET for PTMC between July 2016 and February 2017 were retrospectively reviewed. Indication of TOET was PTMC without capsular invasion or lymph node metastasis on preoperative imaging studies.Ten female patients were enrolled. Seven patients underwent thyroid lobectomy and three patients underwent isthmusectomy. The mean age and tumor size was 43.3 ± 11.5 years and 0.6 ± 0.2 cm, respectively. Operation time for lobectomy and isthmusectomy was 121.1 ± 30.7 (range, 65-148) and 90.0 ± 9.2 minutes (range, 82-100 minutes), respectively. The mean number of retrieved lymph nodes was 2.7 ± 1.7. Two patients had transient vocal cord palsy, which recovered in three months. There was no case with subcutaneous emphysema, surgical site infection, postoperative bleeding, or mental nerve injury.TOET was feasible and could be performed safely for PTMC. TOET might become a new treatment option for the patients who do not want to leave visible scars on the body.

Project description:Following the era of remote access thyroid surgery in the 1990s, several techniques were developed including transoral endoscopic thyroidectomy vestibular approach (TOETVA), which was invented in 2016. TOETVA has gained acceptance and proven comparable results to the conventional open thyroidectomy. Despite the potential complications that may occur as a result of remote access thyroid surgery, such as nerve, vascular, and tracheal injury, seroma, and hypoparathyroidism, there was an extremely rare late complication of a benign subcutaneous thyroid implantation, which have not been reported following TOETVA. A 28-year-old female was developed multiple subcutaneous nodules after undergoing right lobe TOETVA for 2 years due to a 3.1 cm benign nodular goiter. The nodules were excised via submandibular incision and the pathological results were shown as benign. Thyroid tissue implantation may result from intracorporeal thyroid tissue rupture, as reported in this research. Extending the vestibular incision to 2-2.5 cm and partially cutting the specimen within the retrieval bag were options to prevent further tissue damage or spillage during specimen extraction. Meanwhile, a separate incision, such as the axillary or submandibular incision, may be required to retrieve the larger nodules. Even though there were no absolute guidelines or contraindications for patient selection in TOETVA, an awareness of tissue breakage should always be considered. The optimal size of the nodule for vestibular removal, which would minimize the risk of tissue breakage, still required additional research.

Project description:BackgroundAmbulatory thyroid surgery has been increasingly performed in recent years. However, the feasibility of the ambulatory transoral endoscopic thyroidectomy vestibular approach (TOETVA) has not been evaluated. We aimed to evaluate the safety, economy, and mental health outcomes of ambulatory TOETVA.MethodsWe retrospectively reviewed the data of patients who underwent TOETVA between March 2019 and August 2022. The procedure was performed by a skilled surgical team from the Department of Thyroid Surgery of the affiliated Yantai Yuhuangding Hospital of Qingdao University. Patients were enrolled in the ambulatory (n=166) and conventional (n=290) groups, based on their chosen procedure. We analyzed patients' clinical characteristics, surgical outcomes, Hamilton Anxiety Rating Scale (HAM-A) scores, and hospitalization costs.ResultsOf 456 patients, 166 underwent ambulatory TOETVA and 290 underwent conventional TOETVA. No significant differences were found in clinical and surgical characteristics between the groups, including sex (P=0.363), age (P=0.077), body mass index (P=0.351), presence of internal diseases (P=0.613), presence of Hashimoto's thyroiditis (P=0.429), pathology (P=0.362), maximum tumor diameter (P=0.520), scope of surgery (P=0.850), or operative time (P=0.351). There were no significant differences in maximum tumor diameter (P=0.349), extrathyroidal tissue invasion (P=0.516), number of retrieved central lymph nodes (P=0.069), or metastatic central lymph nodes (P=0.897) between the groups. No significant differences were found in complications, including transient hypoparathyroidism (P=0.438), transient vocal cord palsy (P=0.876), transient mental nerve injury (P=0.749), permanent mental nerve injury (P=0.926), and other complications (P=1.000). Ambulatory patients had shorter hospital stays (P<0.001) and reduced hospitalization costs (P<0.001). There was no significant difference in HAM-A scores between the groups (P=0.056).ConclusionsAmbulatory TOETVA is a safe, feasible, and cost-effective procedure for selected patients. This procedure resulted in shorter hospital stays, decreased medical costs, and did not increase patient anxiety. To ensure patient safety, surgical teams must inform patients of the indications, when to seek help, and how to receive the fastest medical attention.

Project description:UnlabelledRecently, a transoral robotic-assisted technique to access the thyroid gland has been introduced. Despite the advantages this approach may have over other minimally invasive and robotic-assisted techniques, we found that the placement of the camera through the floor of mouth led to restricted freedom of movement. We describe our modification to this technique to overcome this problem. In a study using two fresh human cadavers, the camera port of the da Vinci robot was placed in the midline oral vestibule instead of the floor of the mouth. A transoral thyroidectomy and central neck dissection was successfully performed. Our modification led to an unfettered view of the central neck and allowed for a total thyroidectomy and central neck dissection. Our modification of transoral robotic-assisted thyroidectomy provides superior access to the central compartment of the neck over other robotic-assisted thyroidectomy techniques.Electronic supplementary materialThe online version of this article (doi:10.1007/s11701-011-0287-2) contains supplementary material, which is available to authorized users.
